find the image of O(-1, -3) after two reflections, first in the line y = -2, and then in the line x = -2

The image of point O after these reflections is (-3, -1)

Step-by-step explanation:

For a point (x, y) a reflection across the line y = a transforms the point to:

(x, a + (a - y))

and for a reflection across the line x = b, the new point will be:

(b + (b - x), y)

Then if we start with the point (-1, -3) and we do a reflection across the line y = -2

the new point is:

(-1, -2 + (-2 - (-3))

(-1, -2 + 1) = (-1, -1)

now we do a reflection across the line x = -2

Then the new point is:

(-2 + (-2 - (-1)), -1)

(-2 + (-2 + 1), -1)

(-2 - 1, -1)

(-3, -1)

The image of point O after these reflections is (-3, -1)
